I have a 2000 grand prize gtp and my tail light, dash lights, blinkers and head light fuses keeps blowing

well, you have a short somewhere. Here's how to find the cause like a pro does it, or if you don't have such tools disconnect switches at one end and bulb wiring on the other end and pray you find the short that way, fuse will stop blowing when short is disconnected https://www.youtube.com/watch?v=ufVuWznmJLA
